This is a set of STYLE FIT pens, including both 4-color and 3-color sets. The 4-color set includes limited edition patterned refills. The 0.38mm blue, green, red, and black are all limited edition patterns. The pink dot set includes 3 similar pink-toned colors in 0.5mm. I was satisfied with the purchase and forgot about it, so I haven't used them much. However, for some reason, the green and blue inks have run out, even though I haven't used them. It's a mystery since I really haven't used them (・・;) Sometimes there are defective products, so maybe I just got unlucky. I don't know what I'm doing, but I forgot I had these and recently bought a 5-color pen, so I'm listing these for sale (⌒-⌒; ) Feel free to discard the refills if you don't like the colors. I might be transferred, so I'm selling a variety of items. Please be sure to read my profile before purchasing. #uni #colorpen #ballpointpen #stationery
